Announcement: All noncommercial projects registered to use Earth Engine before April 15, 2025 must verify noncommercial eligibility to maintain Earth Engine access.
The geometry used as the left operand of the operation.
right
Geometry
The geometry used as the right operand of the operation.
distance
Float
The distance threshold. If a projection is specified, the distance is in units of that projected coordinate system, otherwise it is in meters.
maxError
ErrorMargin, default: null
The maximum amount of error tolerated when performing any necessary reprojection.
proj
Projection, default: null
The projection in which to perform the operation. If not specified, the operation will be performed in a spherical coordinate system, and linear distances will be in meters on the sphere.
